Add support for detecting recursive blockinherits, and print a trace of
the detected loop. Output will look something like this upon detection:
Recursive blockinherit found:
test.cil:42: block a
test.cil:43: blockinherit b
test.cil:36: block b
test.cil:37: blockinherit c
test.cil:39: block c
test.cil:40: blockinherit a
Additionally, improve support for detecting recursive macros/calls. Due
to the way calls are copied, the existing code only detected recursion
with call depth of three or more. Smaller depths, like
(macro m ()
(call m))
were not detected and caused a segfault. The callstack that was used for
this was not sufficient, so that is removed and replaced with a method
similar to the block recursion detection. A similar trace is also
displayed for recursive macros/calls.
Also, cleanup sidorder, classorder, catorder, sensorder, and in lists at
the end of resolve, fixing a potential memory leak if errors occur
during resolve.
